No, everything is working as it should. I merely wanted to better
understand how decisions are made about displaying the arrows in the
correct direction. It is not obvious from reading TYP files or style
directives how this is done. So if I reword my question again, let's say
you have a dual carriageway. Both lanes have the same oneway=yes tag and
both use the same TYP code. Yet one lane displays the arrows pointing left
to right, while the other lane has them pointing right to left. Either the
Garmin unit or mkgmap has to decide how to draw those arrows.

>From what you are saying, I'm assuming it's the direction the way was drawn
that determines the directionality of those arrows. And furthermore, it is
the Garmin software (and Basecamp) that actually makes the decision based
on information in the IMG file. Is that correct?

Thanks for taking the time to answer....
